Former OU pitcher Jon Gray shut down by Colorado Rockies farm team due to shoulder fatigue Published: September 3, 2014

Former University of Oklahoma pitcher Jon Gray will be shut down from the first-round of the Texas League playoffs, and will not be a September call up for the Colorado Rockies after experiencing shoulder fatigue.

According to The Denver Post, Gray could return to the Double-A Tulsa Drillers in the second round of the postseason, but he'll have to wait on making his major-league debut. The Rockies are currently in last place in the National League West with no chance of making the postseason.

This season, Gray went 10-5 with a 3.91 ERA in 124 1/3 innings. He struck out 113 and walked 41.

"I do have some shoulder fatigue, but I knew it wouldn't feel as strong now as it did back in spring training," Gray told The Denver Post Tuesday during a phone interview. "I knew it would kind of wear down a little. But after having a few days off, it feels really good again. I'm still throwing some bullpens."

Gray was the No. 3 overall pick by the Rockies in the 2013 draft. He was ranked as Baseball America's No. 8 overall prospect in its 2014 Midseason Top 50.
